GRAIN AND SEED SEPARATOB.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed May 2, 1907. Serial No. 371,51.

To all idiom it may conce n:

Be it known that l, ilEINRICfl Menus, a citizenv oi the German Empire, raiding at llraunschval G rmany, have invented new and useful Improvements in Grain and bleed Separators. of which the 'lnllowing is a specilicstion.

lily invention improvements in grain and seed scours-tors oi" the ch. scribed which comprises a cylindrical drum in which are provided eup-sha ied pockets adapted to receive and retain. the seeds of weeds and other impurities of smaller size than the n or seed intended to be clee. red. and the chic ol my invention are, to provide for an improved arra genie-lit oi the said pockets whichwill cat "he seeds of weeds and other small impurl ies to stay therein for a longer time than could be accomplished here ore and thus insure their better elimination, and, to increase the ellicicucy of the ma "l llllO.

. .ttainmyobil red on the draw ing herewith in wl ich Figure 1 is a longitudinal section through an inclined separator drum as herein described, showing at the same time part of its outside; Fig. 2 is part of a trn sverse section through the said drum show] the disposition of certain pa idles liereinbelow relcrred to.

s b th construction illus- To illustrate my invention the drawing shows a cylindrical dr m a wl'iich may be of plain sheet metal. inside of the said drum there are arranged about the inner periphery longitudinal paddles Z) extending from one end of the cylinder to the other, their transverse position being tangentially inclined, and a small space being left between the inner periphery of the cylinder and the outer edges of the tangential paddles to prevent a lodging ol grain. Vl hile heretofore the pockets above referred to for the seeds of weeds and the like were contained chielly in the body oi the drum I provide them in the paddles rei erred to, each paddle being pitted with transversely inclined rounded cavities 7) large enough to receive during the revolution of" pockets will be considerably increased by a protective surface covering ad opted. to withstand the wear of the grain and seed, such surface to be placed upon and suitably connected with a basesliect ol softer material.

To the inside oi the cylinder there may be attached sl nder concave blades 0 laterally projecting into the interspaces of the paddles I), the oiiice of the said smaller blades being to better direct the grain or seed upon the larger paddles.

The remainder of the machine may be of any suitable construction, the drawing showing a trough a to receive the impurities or seeds of weeds eliminated from the gram; in the said trough is a conveying screw f and in its lower end a discharge opening Z. Beneath the said trough there is a chute d which is inclined tangentially and. being at the time parallel with the axle oil. the drum is in a sloping position longitudinally.

The drawing shows further the feeding pipe g, in dotted lines, for the grain; h is the discharge end of the drum, the paddles being at this place provided with slots i large enough to permit the passage of the grain, while the cylinder has discharge openings 7:.

The grain or other seed fed into the drum reaches the compartments formed by the interspaocs between the paddles l) where it is by the rotation of the drum thrown about, some of it dropping upon the chute d from which it is repelled by the force of the rotatory movement and gets in this way between the other compartments. The small and globular seeds of weeds are received in the cavities or pockets referred to where they are through the inclined position of the latter retained until about 45 degrees above the horizontal diameter when they drop into the trough e and are conveyed to the dis.

charge opening Z while the grain or larger seed is by the rotatory movement and inclined position of the drum being moved "forward toward the discharge-end h of the latter.

I am aware that not all of the features shown in the drawings are new and I therefore do not claim all of the foregoing but- What I do claim as new and desire to protect by Letters Patent is:

In the rotatory drum of a grain and seed separator the combination of longitudinal paddles arranged about the inner periphery of the drum, their transverse dimension being tangentially inclined, and secured inthe & In testimony whereof I have signed my ends of the said drum and provided with name'to this specification in the presence of transversely inclined rounded cavities, a two subscribing Witnesses.

small space being left between the edges of HEINRICH MOBUS. the'paddles and the inner periphery of the Witnesses:
